1/x+1/(2x)= 1/5

\frac{1}{x} + \frac{1}{2 x} = \frac{1}{5}

x = \frac{15}{2}

Decimal Notation

x = 7.5

Solution steps

\frac{1}{x} + \frac{1}{2 x} = \frac{1}{5}

Multiply by LCM

15 = 2 x

Switch sides

2 x = 15

Divide both sides by

2

x = \frac{15}{2}

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = \frac{15}{2}

x - \frac{3 x + 5}{x + 2} = \frac{1}{x + 2}

\frac{1}{6} + \frac{1}{y} = \frac{1}{3}

\frac{7 - 3 x}{5 - x} - \frac{2 x}{3 - x} = 8

\frac{x}{x + 2} + 1 = \frac{4}{x ^{2} + 2 x}

F, M = \frac{d}{F}
